Context — As brief as East African linguistic history can get.
Swahili as a language came about
when local Bantu language family
put sprinkled nouns from Arabic throughout
its lexicon. They fit uncannily
by making simply one new class of nouns
for ported words. It matched in syntax and
in structure what the Bantu spoke. Scale down
the breadth of words a speaker need command
to few, with fewer synonyms–voila!
A language meant for trade, and quick to learn
emerged. And thus those following Allah
could come and talk and trade, go and return.
Their commerce spread the language nationwide,
cohesive grout that unified the tribes.
